Osprey Add-Ons help you make the most of your pack. The Solo and Daylite daypacks and Crampon Pocket add capacity and versatility to many of our packs.  The Stow-on-the-Go pieces allow you to carry extra items via easy attachment to virtually any pack.  Our UL Raincover keeps your pack dry without adding weight to your load and the Airporter LZ stows your pack safely while traveling.
